What is a project member?
Project members are your teammates or employees in your team or organization whom you work with daily! They can see all information on Projects and can be invited to collaborate easily on project and activity levels.
Who is an admin?
To explain it simply, an admin is a kind of like a "superuser" who has the ability to oversee the entire workspace, managing everything from users and all the projects to security and billing. This allows one team member (or more if you choose) to manage their team effectively and securely.
Who is a contributor?
A contributor is a type of member with editing access to projects but can not create new projects in a workspace. Furthermore, a contributor doesn’t have access to the playbook:
Edit a project
Add and review documents
Communicate and add attachments
Edit his profile
